In the embodiment disclosed, an elevated tank or reservoir at is employed for holding water or other liquid, andextending downp wardly fromthe bottomthereof, is a fall tube 5, the upper portion of such tube being enlarged, as shown at 6, andgpr'ovided within the lower portion of the reservoir 4 with a valve seat 7.

rests upon the surface of the liquid in the reservoir, said arm being pivotally mounted,

as shown at 26 011 the nozzle 21.

Connected to the fall tube 5, adjacent to the enlargement 6, isa vacuum pipe 27, which extends to any or various pointswith in a building orthe like, as will bereadily understood. Thispipeisclosed at its lower. end, as shown at 28, and atydifferent. Ede

sired-points, has branches29 providedwith i automatically closing flapvalves 30, the said a valves being. carried by socket pieces 31..

These socket pieces are designed to receiver the nipple 32 carried by the flexible hose :33 of a vacuum cleaner tool 34. f i U The supplybranch. 11 is provided with} suitable controllingvalve 35, the stemg36g of i which is connected to a lever 37 mounted on a bracket arm 38thatis suitably clamped to the pipe branch 11. Secured to this bracket 2:

arm 38 is a vacuum chamber 39 that is. in communication with the vacuum pipek27,

through the medium of a pipe 40connected to; both. One wall of this vacuumcliamber,

as. shown in Fig. 3, is injthe form of a flex- 1 ible diaphragm i1, and attached thereto. is a reciprocatory rod 12 that is also pivotally connected to the lever3'7. This rod is'jturlthermore attached to a sliding f plate 43 mounted on. the arms o fwa yokea, whichflf surrounds the pipe branch 11. Also slidablyj mounted on the arms of this yoke, is another plate 45 adjustably maintained in/place d 1 nuts -16 screwed upon the saidarmsmand interposed between theplates 13 and-459B 1a coiled spring 17 thatsurroundsthe rod a.

Briefly described, the operation of .ithe structure is as .followszj Assuming the vacuum pipe 27 closedtothe outside air,.if the valve 10 in the main 9 is opened,water will flow freely: through both branches 11 and 12, until a predetermined amount is. in

the reservoirs, whereupon the ball 25 will be raised sulliciently to permit the, valve 22 to close, and thus cutoff the dischargefof liquid into the reservoir through thebranoh} 12. The branch 11 will-also be discharging liquid into said reservoir, .bnt y-this liquid closed position.

wheel 14., causing the same to revolve and thereby, through the gearing, turning the cam 17. The raised portion 18 of said cam will operate against the underside of the collar 19, thereby lifting the valve 8 until said raised portion has passed the collar. As a r sult, the liquid Wlll flow from the reservoir into the fall tube 5 until the valve 8 is released, whereupon it will drop to This valve, it will be noted, will be intermittently or periodically operated, permittingsho-rt plugs, columns or pistons of water spaced from each other to pass downwardly through the fall tub-e 5, carrying between them, bodies of air. The only place that this air is supplied from, is the-pipe 27, and as a consequence,

a p'artial vacuum will be created in the said pipe 27. It will thus be evident that if a pneumatic tool or other device is attached to said pipe, air will flow therethrough and into thesame; In the case of apneumatic tool, air in a dust-laden condition, will be taken into the tube 5 between the sections or pistons of water and be carried off, the discharge from said pipe 5 being preferably into a sewer. /Vhen a predetermined vacuum is secured in the pipe 27, either by the entire closing of said pipe, or by the greater amount of air taken therefrom to that admitted, the diaphragm 41 of the vacuum chamber will be forced inwardly sufficiently to cause the valve 85 to be closed, thus stopping the operation of the motor 14:, and consequently permitting the valve 8 to remain inits closed position. The operation therefore is substantially automatic,

and in this connection, it may be stated that the projection 18 of the cam 17 is such that 1t will not stop on a dead center with the valve .open. its soon as said projection 18 passes the collar 19,..the collar is free to drop,.and should itstop at any point on the front rounded surface, the weight of the valve will be sufficient to cause a rearward movement of the cam and motor to insure the closing of the valve.

Z .jFrom theforegoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, withp out further description, and it will be understood that various changes in the size,

shape, proportion and minor details of construction may be resorted to without departmg fromthe spirit or sacrificing any of the advantages of the invention.
